Replacing a car battery on older vehicles used to be simple!! You unhook the old battery and install the new one. Late-model vehicles, however, rely on computers that operate everything from the stereo to the transmission. If power is lost to the computer, the settings are lost and have to reset to default. That means the vehicle may feel different when driven, and you may have to enter a security code to access the stereo. Using this simple memory saving device when replacing your car battery will help you avoid these problems.
This device can work with any 12V DC power source, including jump starter, DC 12V Lead-acid battery, or another car's DC 12V power outlet.As our device with 3 meter cable, it will be a convenient way, should you not have jump starter (or Lead-acid battery) on hand, and the device can also get the 12v power supply from cigarette lighter of another good car. Just insert the Cigarette lighter plug to this car and insert into 16 pin plug to the OBD port of the car you want to replace battery. And now you can replace the battery.

1 X OBD II CAR MEMORY SAVER with Cigarette Lighter Connector, cable length 3M(10ft)
